[Detailed description of the invention]

[0001]

INVENTION The present invention relates to a quarto, superimposed in various aspects, such as overlapping Ri switching, by adhering the overlapping surfaces releasably, notice, postcards, and overlay sheets of card or the like The present invention relates to a sheet with an adhesive.

[0002]

2. Description of the Related Art Conventional sheets with an adhesive include:
After applying a pressure-sensitive adhesive with constant adhesive force to the sheet surface,
Those coated with release paper, or usually do not adhere,
There is known an adhesive applied to a sheet surface, which can be adhered when given adhesive conditions are given.

[0003]

However, the conventional sheet provided with an adhesive coated with release paper on the sheet surface becomes thicker due to the presence of the release paper, and is not suitable for performing various processes such as printing with a printer. It is not suitable for the feed operation, is difficult to handle, and has the drawback that it is extremely difficult to set the adhesive force to be peelable. Further, those provided with an adhesive which can be adhered when a given adhesive condition is given to the sheet surface are generally easy to handle, but similarly to the pressure-sensitive adhesive, it is difficult to adjust the adhesive force, and If the force is too strong, the adhesive surface will be damaged at the time of peeling. On the other hand, if the adhesive force is too weak, the adhesive surface will be easily separated, making it impossible to use the laminated sheet as desired. An object of the present invention is to provide a sheet with an adhesive which uses an adhesive which does not normally adhere and which can be peeled off under a certain condition, which solves such disadvantages.

In order to achieve this object, the present invention relates to a sheet with an adhesive which is folded, cut and laminated, or a separate object is laminated, and the laminated surface is peelably adhered to form a laminated sheet. there, of a predetermined size 1
The unit of the sheet for superimposition is divided into four substantially equal sections by a folded portion or a cut portion extending in the vertical and horizontal directions, and a predetermined section adjacent to the same surface on each of the front and back surfaces is defined as a superposed surface,
It is possible to print or print on a predetermined portion of this overlapping surface, and it is not normally adhered, it can be adhered when certain conditions are given, and it can be peeled off after bonding without damaging the printed or printed For this purpose, a non-peelable adhesive base, which is difficult to remove once adhered, is mixed with a fine-grained filler that has incompatibility with this adhesive base, and an adhesive whose adhesive strength is adjusted is applied. It is. In the present invention, printing or printing of entry fields and information on the adhesive provided on the sheet is performed as needed, and need not always be performed.

[0005]

The adhesive for adhering the superposed surfaces divided in a predetermined manner is not usually adhered, but can be adhered under certain conditions. Since it can be peeled off without damaging the printing,
When the sheets are superposed in a predetermined state and given a certain bonding condition, a superposed sheet is obtained in which the superposed surfaces are releasably bonded. On the other hand, when information or the like is printed or printed on the superposed surface to which the superposed sheet is bonded, when the bonded surface is peeled off, the printing or printing of the information or the like is not damaged and can be visually confirmed without fail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment in which the present invention is applied to a sheet with an adhesive for producing a reciprocating postcard will be described in detail with reference to the accompanying drawings. Here, FIG. 1 is a plan view showing the front side of the adhesive-attached sheet, FIG. 2 is a plan view showing the same back side, FIG. 3 is a plan view showing the transmission / reception destination side folded in half, and FIG. 5 is a plan view showing the reply destination side, FIG. 5 is a cross-sectional view showing the created reciprocating postcard, and FIG. 6 is a flow chart showing a process for creating a reciprocating postcard from the adhesive sheet.

A sheet 1 with an adhesive shown in FIGS. 1 and 2
Is formed by dividing an A4-size sheet for superimposition into four equal parts by a folding perforation 2 and a folding / cutting perforation 3 orthogonal to the folding perforation 2. By the folding and cutting perforation 3, the mail is divided into an outgoing postcard portion 4 and a reply postcard portion 5. Further, by the folding perforation 2, the outgoing postcard destination portion 4a, the outgoing postcard communication portion 4b, and the reply postcard destination portion 5a are returned. It is divided into four sections with the postcard communication section 5b. Then, on the front side of the outgoing postcard destination part 4a and the reply postcard destination part 5a,
An outgoing credit address writing section 6 and a reply outgoing credit address writing section 7 for writing addresses are provided. A slit 8 is provided along the edge of the postcard 4 opposite to the perforation 3 for folding and cutting to facilitate the peeling operation after bonding.

As shown in FIG. 1, on the front side of the adhesive-attached sheet 1, the outgoing postcard communication section 4b and the reply postcard destination section 5a form an overlapping surface on which the folding and cutting perforation 3 is folded. ing. On the other hand, as shown in FIG.
In a rear surface of the adhesive-backed sheet 1, Oshin postcard destination portion 4a and replies postcard communication unit 5b becomes the first compartment, as well
Each of the outgoing postcard communication section 4b and the reply postcard destination section 5a, which is one section, has a superimposed surface that can be folded from the folding perforation 2. An adhesive 9 is applied to the superposed surfaces 4b and 5a on the front side, and an adhesive 10 is applied to the superposed surfaces 4a and 5b and 4b and 5a on the back side.
Are applied over the entire surface. The adhesives 9 and 10 are the same.

Each of the adhesives 9 and 10 can be printed or printed, and does not usually adhere, but can be adhered under certain conditions, and does not impair the printed or printed after the adhesion. It is releasable in such a way that once it is adhered, it is difficult to remove again , for example, a pressure - sensitive non-peelable adhesive base is mixed with a fine-grained filler exhibiting incompatibility with this adhesive base made also because. In the case of a pressure-sensitive adhesive, it is 50 kg or more, preferably 80 kg / cm ^2.
It is preferable that the adhesive be applied at a pressure of Kg or more.

The adhesive base may be a conventional pressure-sensitive adhesive which has been conventionally used. In particular, a natural rubber obtained by graft copolymerizing styrene and methyl methacrylate on a natural rubber is used. Latex is preferred in terms of blocking resistance, heat resistance, abrasion resistance and the like. In addition, as the adhesive base, in addition to pressure sensitivity, a conventional heat-sensitive or rewet adhesive that has been conventionally used can also be used. As the heat-sensitive adhesive base, particularly, a vinyl acetate polymer is used. Is preferable, and as the rewetting adhesive base, polyvinyl alcohol, polyethylene oxide and the like are preferable.

On the other hand, as the finely divided filler, those having a small affinity with the adhesive base, for example, zinc oxide, titanium oxide, calcium carbonate, kaolin, activated clay, spherical alumina, wheat starch, silica, glass Powder, shirasu balloon and the like are used. These materials are
A single material or a combination of a plurality of materials may be used, but a combination of silica and another appropriate filler is particularly preferable. Further, when two or more kinds having different particle diameters are combined, the adhesive-applied surface is easily formed in an uneven shape, so that the peeling performance is improved. Addition of silica has the advantage that the coating of the adhesive can be reinforced and the porosity of the adhesive makes it easier for the adhesive to adhere to the surface, so that the adhesive force and the peeling force can be easily adjusted. Further, even when printing is performed by a printer using silicone oil in a non-impact printer system, the silica absorbs the silicone oil, so that the adhesive does not become stuck by the silicone oil.
The average particle size of the fine particulate filler is 10 mμm to 3 μm.
The range of 0 μm, preferably 1 μm to 20 μm, and more preferably 2 μm to 15 μm is suitable.

The above-mentioned finely divided fillers can be used for any of pressure-sensitive, heat-sensitive and rewet adhesive bases, but not for pressure-sensitive and rewet adhesive bases. , 100 parts by weight of the adhesive base and 100 parts by weight of the fine particulate filler.
It is desirable to add the compound in an amount of from 400 to 400 parts by weight, preferably from 130 to 300 parts by weight, most preferably from 150 to 250 parts by weight. For the heat-sensitive adhesive base, 45 to 10 parts by weight of the fine particulate filler is used for 100 parts by weight of the adhesive base.
0 parts by weight, preferably 55 to 90 parts by weight, and most preferably 60 to 80 parts by weight.
When the compounding ratio of the fine particulate filler is less than the above range, the blocking resistance is inferior, and the adhesive force is too strong, while when the amount is more than the above range, the adhesive force is excessively reduced and easily peeled off. Would.

Further, the adhesive-attached sheet 1 comprises adhesives 9 and 10.
Is applied, the smoothness is JISP-8119
20 to 120 seconds, preferably 30 to 70 seconds,
More preferably, it is in the range of 40 to 60 seconds, the air permeability is 100 seconds or less in accordance with JISP-8117, the peel strength is 1 kg / cm ² , and a 25 mm width after leaving for 30 minutes at room temperature. It is desirably 10 g or less.
Generally, when an adhesive is applied on a sheet, irregularities are generated on the surface, and the irregularities on the surface of the adhesive fall off due to rubbing or the like, or become a source of paper dust during a printing step, a printing step, or during storage. In addition, non-uniformity and unevenness of ink fixation in printing and printing occur. Therefore, when the smoothness is set in the above range by a process such as calendering, the above-mentioned inconvenience is solved and both printability and printability are excellent. Further, when the air permeability is in the above range, the transfer of the postcard sheet 1 using a transfer device or the like having a suction action is smoothly performed, and the moisture-evaporating is sufficiently performed, so that the adhesive-attached sheet 1 may curl. When the peeling strength is within the above range, the adhesive-attached sheet 1 can be surely adhered, and at the same time, can be peeled off without impairing the printing or printing performed on the bonded superposed surface. In this embodiment,
The proportions of finely divided fillers, smoothness, Ru can be adjusted air permeability and peel strength.

The sheet with adhesive 1 is in the state shown in FIG.
After the concealment information 11 is printed on the back side of the outbound credit destination section 4a by a printing device (not shown) (see FIG. 2),
Similarly, an address 12 is printed on the outbound address entry section 6 by a printer (not shown) (see FIG. 3). Subsequently, after folding is performed by the folding perforation 2 so that the superimposed surfaces on the back side are overlapped with each other, the concealment information 13 is printed on the front side of the incoming credit communication unit 5b by a printer (not shown) (FIG. 3 and FIG. 4). Then, at the folding / cutting perforation 3, the sheets are further folded in two so that the overlapping surfaces on the front side overlap each other, and a pressure, which is an adhesive condition of the adhesives 9 and 10, is applied to each overlapping surface. Are peelably adhered to form a four-fold reciprocating postcard 14 as shown in FIG.

As shown in FIG. 6, the postcard 14 has the adhesive 9, 9
An adhesive application step for applying the adhesive 10, a printing step for printing the concealment information 11 on the adhesive 10 on the overlapping surface, an information printing step for printing the concealment information 13 on the adhesive 10 on the overlapping surface, It is created by sequentially performing a superposition step of folding one superposed surface of the sheet and a bonding step of applying the bonding conditions of the adhesives 9 and 10 and releasably bonding the superposed surfaces.

As shown in FIG. 5, the created postcard 14 is in a state in which the concealment information 11 and 13 are not visible from the outside, but can be posted in the same manner as a normal postcard.
Although not described or illustrated in the above-described creation process, the concealment information 1
Explanations for viewing 1, 13 are displayed at appropriate places in advance. Therefore, the addressee who received postcard 14
When the slit 8 is broken to make it easier to put a finger, the concealment information 13 is visually recognized by applying a force of a certain degree or more to the adhesive surface between the outgoing communication unit 4b and the reply destination unit 5a and peeling it to make the spread state. (See FIG. 4). Furthermore, if the outgoing postcard portion 4 and the reply postcard portion 5 are separated at the folding / cutting perforation 3, and the outgoing postcard portion 4 is peeled open, the concealment information 11 can be visually recognized (FIG. 2). reference). At the time of these peeling, since the adhesive strength of the adhesives 9 and 10 is set so as to be peelable without impairing the printed or printed, the concealment information 11, 1 is used.
There is no danger that 3 will come off and will not be visible.
Further, the stripping operation is easy due to the slit 8. On the other hand, if the address and the communication message are described in the separated reply postcard part 5, it can be posted as a reply postcard.

[0017] The present invention is not limited to the embodiments described above, for example, as a method of providing a adhesives 9, 10 on the seat surface, it is impregnated in the step of combing the sheet,
It may be one that is exposed on the sheet surface. Further, instead of the slit 8, a perforation, a notch, or a knob protruding from another portion may be provided to form a finger hook portion to facilitate the peeling operation. Further, the portion where the adhesives 9 and 10 are provided is not limited to the entire overlapping surface, but may be a part thereof. The adhesive of the present invention does not adhere unless certain conditions are applied, so even if it is applied to the entire front and back of the sheet,
It is convenient without interfering with handling. In addition, the present invention can be applied not only to folding but also to the sheet 1 with an adhesive to be cut and overlapped. Further, the overlapping sheet to be created can be applied to not only postcards but also various cards and various forms. Of course. Further, the material of the sheet with adhesive 1 can be appropriately selected from ordinary paper, synthetic paper, resin film, and the like. In addition, the concealment information 11 and 13 of the present invention are not particularly required to be confidential.
For example, spread advertising information that requires a large printing area may be used.In this case, if the owner of the concealed information opens and the information content is viewed on both sides of the spread, it attracts the recipient's interest and is used as direct mail, etc. The advertising effect can be further improved. Also, by providing printing, the adhesive strength of the printed portion can be made lower than that of the other portions. However, in order to maintain the reliable adhesive strength of the adhesives 9 and 10, dots, lines, and solid portions are required. The printed area is preferably 75% or less, more preferably 50% or less of the adhesive surface, and the ratio of solid printing to the printing area is preferably 25% or less. Further, the concealment information 11 may not be provided.
